Ich soll ausrichten, daß ist ein völlig v******* Scheinwerfer, den hat ein absoluter V***** konstruiert und nur noch größere W******** würden so was kaufen.

(Tja, nun)

Und nun ist er zwar fest, der Scheinwerfer, aber um 15 Grad gedreht, da stimmt das natürlich mit dem v******* Fern- und dem k****** Abblendlicht nicht.

V******** S*****.

Aber morgen, da nimmt er die Bohrmaschine, und dann wird das passend gebohrt, das ***** ******.

Da kann es sich mal umsehen!

(Himmel, eigentlich ist der Mann hier der ruhende Pol im Haus....)

All the molds for the concrete are hand cut from foam and the lamps are hand sanded which results in minor differences per lamp. The biggest differences are in the cover plate. Therefore you can choose from three variants.

#Skyglow reductions observed during #EarthHour in #HongKong imply that #LED billboards and building façade lighting are "major contributors to urban light pollution."

NatureNatural experiments from Earth Hour reveal urban night sky being drastically lit up by few decorative buildings - Scientific ReportsLight pollution, a typically underrecognized environmental issue, has gained attention in recent years. While controlling light pollution requires sustained efforts, Earth Hour offers a unique natural experimental setting to assess temporary lights-out measures. Using photometric and spectroscopic sensors, we observed up to 50% night sky darkening during Earth Hour from 2011 to 2024 in Hong Kong, primarily as a result of a small but critical number of lights-out instances in central business districts, as evidenced by crowd-sourced photography records. Weekend lighting pattern in the city during Earth Hour remained unaffected. The emission reductions mostly occurred in the 445–500, 500–540, and 615–650 nm spectral ranges—corresponding to peak emissions from LED billboard screens— and in the 585–595 nm range, associated with metal halide floodlights used for facades and billboards. Our study identifies these sources as major contributors to urban light pollution. By combining multimodal observations, we offer a comprehensive assessment of light pollution sources and the potential benefits of sustainable lighting practices in urban environments. This research highlights the importance of targeted light pollution mitigation efforts and provides critical insights for policymakers to enhance urban sustainability and human well-being.

@3dprinting Then I started thinking about how to route the wires and what connectors and where to locate the MCU and which door sensors to use and it's just too much to figure out today.

I've got a long list of features I want to put into this cabinet. Lighting, fan, temperature/humidity, door sensors, knock sensor, an LCD display, and the dehumidifier. Maybe I should figure out a way to add features incrementally. But they're all interdependent.

@3dprinting The plan is to have this aluminum channel running up the center of the FilaBilly Humidor. It will provide a surface for the door to seal against (I hope) and also hold an LED strip to light up the interior.

I got this far in modeling and printing the clip that holds the LEDs in. (cont'd)

Solo vengo a decir que si no escribo mucho y no aparezco por acá, es porque estoy escribiendo la tesis fuerte, o complicado con el laburo. También vine a decir que los focos LED esos blancos que les ponen a los autos ahora, no a los eléctricos, a los autos más viejos, con los porta lámparas que están pensados para las de filamento, cagan todo y encandilan 4 veces más, no sean terrajas. Déjense de joder y vuelvan a las lámparas halógenas. Los autos eléctricos tienen otro diseño en los difusores, encandilan un poco menos (solo un poco) pero al ser tan puntuales los LED parece que te están haciendo guiños con las largas todo el tiempo. Si no me voy a poner una lámpara en el techo yo y voy a empezar a devolver los encandilazos a diestra y siniestra #yameiba #autos #led
